| Abstract: | The activities of 210Po and 210Pb were determined in commonly consumed seafoods to evaluate the internal exposure and risk to humans residing Kudankulam coast where a mega nuclear power plant is under construction. The concentration of 210Po in seafoods ranged from 1.2 ± 0.7 to 248 ± 8.1 Bq kg−1. Meanwhile, 210Pb ranged between 1.1 ± 0.05 and 14.8 ± 1.6 Bq kg−1. The committed effective dose (CED) due to 210Po and 210Pb varied from 11.04 to 515.6 and 3.93 to 23.5 μSv yr−1, respectively. The lifetime cancer risk for the public due to 210Po was in the range of 3.47 × 10−5-1.62 × 10−3 and it was 4.03 × 10−5-1.96 × 10−4 due to 210Pb. The activity intake, effective dose and cancer risk was found lesser than international guidelines and the seafood intake was considered to be safe for human consumption. |
